Non Conventional Machining Process Ppt -
No direct contact between the tool and the workpiece (in most cases).
If you are converting this guide into a , organize your slides around these core sections using the clear hierarchies provided above.
Replacing toxic dielectrics (like hydrocarbon oils in EDM) with biodegradable options, dry gas dielectrics, or pure water to reduce environmental impact.
Traditional machining methods, such as turning, milling, and drilling, rely on physical contact between a harder cutting tool and a softer workpiece. These conventional methods fail when processing advanced engineering materials like superalloys, ceramics, composites, and heat-resistant steels. Non Conventional Machining Process Ppt
| Parameter | Conventional | Non-Conventional | | :--- | :--- | :--- | | | Harder than workpiece (HSS, Carbide) | No physical contact or softer/conductive material (e.g., graphite) | | Mechanical Forces | High clamping forces required | Very low or zero forces | | Heat Generation | Frictional heat in shear zone | Controlled heat, or no heat (ECM, USM) | | Geometric Complexity | Limited by tool access | Virtually unlimited (holes at angles, micro-features) | | Material Hardness | Cutting becomes impossible above 45 HRC | No correlation with hardness |
Non-conventional machining processes are essential for modern manufacturing. By using well-structured presentations, you can effectively explore their key roles and applications.
Uses electrical sparks to melt and vaporize material. No direct contact between the tool and the
Material is selectively dissolved by controlled chemical etching. Chemical Machining (CHM) / Chemical Milling 3. In-Depth Analysis of Major Processes Mechanical: Ultrasonic Machining (USM)

This is where processes, also known as Advanced Machining Processes (AMP) , step in. For educators, students, and industry trainers, creating a high-impact Non Conventional Machining Process PPT is essential to visually and conceptually explain these complex, energy-based material removal techniques.

Material is removed via atom-by-atom electrochemical dissolution.
This process uses a tool vibrating at a very high frequency (around 20 kHz) to drive an abrasive slurry against the workpiece. The combined action of the vibration and the abrasive particles chips away tiny fragments of material from the workpiece, which must be hard and brittle (like ceramics or glass).
